TOASTER.

SPECIFICATION forming part of Letters Patent No. 579,050, dated March 16, 1897.

Application filed October 8, 1896. Serial No. 608,211. (No model.)

To aZZ whom it may concern.-

Be it known that I, AROI-IIBALD FAIR GRIEVE, tinsmith, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Toasters, of which the following is a specification.

My invention relates to improvements in bread-toasters; and the object of the invention is to design a simple, cheap, and efficient toaster, more particularly for use over gasstoves, in which it will be impossible for the bread to be reached by the flame and be impregnated with the gas in such flame; and itconsists, essentially, in making the toaster preferably in ring form of peculiar construction and providing a diaphragm made of flat sheet metal provided with perforations, a suitable wire handle being provided for the reception of the toast, as hereinafter more particularly explained.

Figure 1 is a perspective ,view of a toaster made in accordance with my invention. Fig. 2 is a section through the toaster.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is the ring, which is made, preferably, of sheet metal and in two portions A and A The top portion A has U-shaped bottom edge a extending entirely around the periphery.

B is a diaphragm made of sheet metal having perforations I). These perforations are shown in the drawings exaggerated both as to size and as to distance apart, they being in reality very close together. The diaphragm B is formed of perfectly flat sheet iron or metal tinned. The outer edge I) is U-shaped and fits within the U-shaped lower edge a of the upper portion A. The lower portion A has an outwardly-extending lip a which fits within the U-shaped edge 1), formed at the edge of the diaphragm B.

In assembling the parts the upper lip on the lower ring has the U-shaped portion of the diaphragm spun around it, and this is fitted underneath the upper ring, the lower edge of which is spun up so as to'form a U- shaped portion and securely binds the diaphragm and the previously-held lip in position.

All the parts are secured firmly together in a simple and economical manner.

C is a handle which is made of awire which extends through suitable openings in the up per portion A across the ring at a desired distance above the diaphragm B. The inner end 0 of the handle C forms a rest for the reception of the toast. A sheet-metal grip C is provided outside the ring for convenience in grasping the handle when using the toaster.

I am aware that similar handles have been made for similar articles.

I am also aware that sheet metal has been used unperforated for toasters, and I am also aware that wire mesh has been used, and I do not lay claim, broadly, to any such device. In toasters in which the wire mesh is used, however, it is well known that when the flame is turned on too-strongly, which is quite a common occurrence, a certain amount of the gas fumes escape and pass through the mesh, giving the toast a gaseous taste and smell. In the form of toasters also in which the wire mesh is used such mesh will on account of the expansion and contraction of the wire of which it is formed soon break and burn out, leaving still larger spaces for the gas fumes to come through and thereby ren dering the mesh of the toaster useless in a very little time.

In providing my toaster with a diaphragm comprising a sheet of iron with perforations I find after a great deal of experiment and subjecting my toaster to the severest test that the flame impinging upon the flat surface is defiected and kept beneath such surface, so that it is utterly impossible, no matter 110w strong the flame maybe turned on, for such flame to pass through the perforations in the diaphragm; Consequently in the use of my toaster all danger from the rapid burning of the toast or the impregnating it with gas is entirely obviated. Again, in my toaster I also find in practice that the expansion and contraction of the metal is such that the diaphragm willnot under any circumstances become broken and wear out,

thus insuring a durable article for the purpose herein set forth.

Although the flame in my toaster will not go through it Will be readily understood that the heat passes readily through the perforations, thus providing much more rapid and even results in the cooking of the toast With very much less consumption of gas than any toaster of Which I am aware.

WVhat I claim as my invention is- 1. A toaster comprising a cylindrical body, a perforated diaphragm arranged centrally thereof, said body having a slot in the Wall thereof above said diaphragm and a rest formed of Wire doubled intermediately the ends thereof being secured in the wall of said body opposite to said slot, and the bail portion thereof being extended through said slot ARGHIBALD l AIRGRIEVE.
